The 304-pound television is the largest TV on the market and includes built-in WiFi and a full web browser, according to a spokesman for the company.

The television, dubbed the "ultimate TV," went on sale Tuesday at Abt Electronics and Appliances in Glenview. The retailer will be the exclusive seller of the television for the next six months, the company said.

Officials said one television has already been sold to a North Shore resident.
